To all whom, it may concern.-

Be it known that I, ZENAs F. BRYANT, a citizen of the United States,residing at Malden, 1n the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inCurtain-Fixtures,I of which the following is a specification.

My invention relates to improvements in curtain-fixtures provided with aspiral spring for rolling up the curtain', and apawl and ratchet ornotched hub for checking the rotation of the roller; and it consists inthe improved devices and combinations hereinafter set forth, andspecifically pointed out in the claims.

In the drawings, Figure l-is a plan view of the exterior of so much of acurtain-fixture as is necessary to illustrate Iny invention. v Fig. 2 isa longitudinal section of the roller, showing the parts therein. Figs.`3and 4 are per# spective views of the two brackets; .Fig.'5 shows the endof the cap and spindle having the pawls thereat.l Fig. 6 shows a portionof the roller at the end, the cap being removed. Fig. 7 is an end viewof the roller, the cap being removed, and also shows the spring andsection of the spindle. Fig. 8 shows an end of the iiuted cap. Fig. 9shows the spindle.

The wooden roller A has a central hole extending therein from one end ofthe roller a sufficient distance for the required spring B. This holemay be of much smaller diameter than ordinarily required, on account ofthe small diameter of the spindle G and of the spiral spring B. Theinner end of this hole tapers at a toward'the axisof ythe roller, andhas a smaller portion at b. This part'b, ofV smaller diameter, receivesthe end of the spin! dle C, which bears therein. The tapering part aguides the end of the spindle into its bear ing b when thrust endwiseinto the hole in the roller. The spindle C has fastened thereon aratchet or notched hub, e, in which the notches upon opposite sides ofthe hub are'formed by grooving the end of the hub diametricallybefore'it is placed on the spindle. The outer end, d, of the spindle isformed rectangular, to be held inthe socket e of the bracket D, so thatthe spindle is prevented from revolving. One

end of the spiral spring B is fastened to the spindle, near'its innerend, at f. The 'other end of the spring-wire is fastened to the rollerSerial No. 163.6136. (No model.)

bybeing bent of suitable shape to extend through a slot, g, a'peripheralgroove, h, andA a slot, t', asshown. v

The cap E covers an end of the roller A and extends a distance over itsperiphery, so as to cover the groove h and the spring-wire therein. Thiscap', which may be strucknp out of sheet metal, is of double thicknessat its outer end--that is, the thin metal is turned back upon itself, sothat the cap is recessed or countersnnk at its end to form a chamber forthe pawls j. Each of these pawls is pivoted by means of a pin, k, (whichmay be a simpleround 'nail or a screw,) which extends through the end ofthe cap and into the wooden roller at l. These pins will keep fthe capin place on the roller, as well as serve as pivots for thepawlsJQwingto' the smalldiameter of the spindle and spring, and Vhencevof the hole in the roller, the shell ofthe roller is quite thick, so asto receive the pins k, as shown. The cap F at the other end of therolleralso covers a large part of they end ofthe roller and extends over aportion of its periphery. It is longitudinally fluted atfml throughout aporf vtion of its periphery extending to its` outer of the roller may begaged, and 'also by which the disk or plate n may be held vIirnnl y. Theuting also gives stiffness to the outer edge of the cap, so that it maynot be easilyfbent or jammed.l

In order to provide a small spindle and one 'having the desired strengthand stiffness, lI preferl to construct the vsame by winding a wire, o,around a central core, x. The wire'o is bent to form the rectangularendd. The central wire or core, w, may be doubled or en-4 larged withinthe ratchet or notched hub c, and extends beyond the wire 'v to form theinner end of the spindle -in the bearing I claim as my invention- Ioo"y 1. In combination With a curtain-roller, A, having slots g and z' andperipheral groove h, and a spindle, C, a spiral spring, B, fastened atits inner end to the spindle and fastened at its outer end to the rollerA by extending through said slots and groove, substantially as setforth. y

2. In combination with a curtain-roller, A, provided with slots g and iand groove h, to receive the end of the spring-wire, a cap, E, extendingover the periphery of said roller, so as to cover said groove andspringwire therein, substantially as specified.

3. In combination with a curtain-roller, A, a cap, E, of one piece ofmetal, extending over a portion of the periphery of said roller andturned back upon itself at its outer end,Whereby the cap may be struckup out of sheet metal` and be recessed or countersunk at its end to formaicharnber for the pawis j, substantially as specified.

4. In combination with a curtain-roller, A, cap E, and pawls j, pins 7c,which extend through the end of said cap and into the roller and formpivots for the pawls, substantially 25 as set forth.

5. In acurtainroller, in combination with a ratchet or notched hub, aspindle formed of a central wire or core doubled or enlarged Within theratchet or notched hub, and a wire 3o wound around the central wire orcore and bent to form the rectangular end, substantial] y as specified.

6. In combination with a curtain-roller, a spindle therein formed of acentral core hav- 3g ingawire wound thereon, substantially as described,and for the purposes set forth.
